SPRAY PRODUCING SCOOP FOR WATER-BORNE OBJECTS Filed June 4, 1957 /9 Q/N|/ENTOR:

THOMAS B. MODINE ,4 TTOR/VEV United States SPRAY PRODUCING SCOOP FORWATER-BORNE OBJECTS This invention relates to a novelty item for usewith boats or like water-borne objects to create a streamof water. 1 7

It is an object of this invention to provide a means whereby a stream ofwater can be created when said means is attached and properly disposedwith regard to a water-home object moving through Water.

Another object of this invention is to provide a means of the noveltytype which can be readily and easily attached to the rear of a motorboat, the motor, water skis, or the like object, and which isinexpensive but yet'adjustable, and all for the purpose of creating astream or spray of water directed high above and behind the object whenthe latter moves through the waters Another object of this invention isto provide a novelty which accomplishes the foregoing objects with saidmeans being readily movable out of an operating position and into aninoperative position. I

Other objects and. advantages will become apparent 'upon reading thefollowing description in light of the accompanying drawings, wherein:

Fig. 1 is a perspective view of a motor boat with the device of thisinvention attached to the rear thereof and showing the water streamcreated by said device.

Fig. 2 is an enlarged top view of the device shown-in Fig. 1 and viewedalong the plane indicated by the line 22 of Fig. 3, and showing afragment of the boat motor.

. is the device, generally designated 12, which constitutes theembodiment of this invention," and it will be noted that the device isattached by means of a bracket 13 to the boat motor 11 on the boattransom 14. The bracket 13 is shown attached to the motor 11 by means ofthe four bolts 15 to secure the bracket in a fixed-position. It shouldbe further understood that the view assumes that the boat is movingforward through the water, and the device 12, therefore, creates thewater stream or spray depicted to begoing upwardly and rearwardly of theboat. Of course, this device is of a novelty type, and it will beappreciated that such a stream or spray of water creates an extremelyinteresting, aswell as pleasant, view in addition to creating'the effectof high speed of the boat since, heretofore, only the boats of thehydroplane type have created a rear stream or spray due to their extremehigh speed. It should be further understood that a pair of the devicesor items 12 could be attached, one to each side 2,983,508 I Patented May9, 1961,

Also, the device could be attached to water skis, surf boards, and otherwater-borne objects.

Fig. 2 shows a fragment of the motor 11, and it further shows'a mountingplate 16 to be provided with an arcuate .slot 17 and two spaced apartand rearwardly projecting pieces 18. It will also be noted that theextreme rear ends of the pieces 18 are each provided with asemi-circular opening 19, and Fig. 3 shows the opening 19 to extend thelength of the pieces 18 such that the screw 21 can pass through theopening 19 and through the plate 16 to attach into the bracket 13. 'Aswill be more apparent hereinafter, the screw 21 is utilized as aretaining screw for mountingthet item onto the boat transom, and

it is also utilized as a pivot screw for the item. Similarly,

a thumb screw 22 passes through the arcuate slot 17 to thread into thebracket 13 such that the two screws 21 and 22 secure the plate 16 to thebracket 13, and it will now be apparent that loosening of the screw 22will per- .mit the plate 16 to be pivoted about the lower screw 21 byvirtue of the slot 17, and thus the plate 16 and the entire item 12 canbe disposed in any selected tipped or pivoted position with respect tothe longitudinal direction of the boat 10.

As mentioned, the pieces 18 are spaced apart, and the therefore, receivea flat piece or connecting arm 23 which extends to a position adjacentthe bracket plate 16, at which pointa pivot bolt 24 passes through thepieces 18 and; of course, through the plate 23 to secure the latter tothe mounting bracket and provide the pivot axis for the plate 23.vAnother thumb screw 26 threads into one of the pieces 18 to abut thenear side of the plate 23, as shown in Fig. 2, and to thereby retain theplate 23 in a fixed pivoted position by virtue of the abutting orclamping force of thenut onto the side of the plate 23. A member orscoop 27 is attached to the rear end of the plate 23 to move therewith,and it will be noticed that the scoop 27 includes a rear portion 28 andside portions 29 and afront portion or cross bar 31. The side portions29 are shown to converge toward the upper end thereof and, ofcourse,.there is no bottom portion, or it may be stated that the bottomof the scoop is open.

In the full line position shown in Fig. 3 the rear portion 28 presentsan upwardly and rearwardly inclined surface, the lower end of whichextends down intothe water andfbelow the surface line indicated Sfandshown by a dotdash line in Fig. 3. When it is desired to raise the scoop27 out of the water, the thumb screw 26 can be loosened and the scoopwith the plate 23 can be pivoted to the raised position with front edgeof the plate 23 engaginga lower hole in the pieces 18, such as shown inFig, 3, so that the net result is that the scoop 27 will be placed inthe dot-dash line position shown in Fig. 3. In, the latter mentionedposition, of course, the scoop 27 willnot create the stream or spray ofwater, such as indicated in Fig. 1, and the device is, therefore, in aninoperative position. Since the lower ends of the sides 29 are fartherapartthan the upper ends of the sides, the

the scoop and will be formed into a stream of a shape indicated by thebottom 28 and the sides 29.

By virtue of the thumb screw 26, the scoop 27 can be placed in selectivepivoted positions such that the bottom 28 will be inclined at an anglewhich will present a desired spray of the water and, of course, byvirtue of the thumb screw 22, the spray can be directed to one side orthe other with respect to the longitudinal direction of the boat.Therefore, the two adjustments provide adjustment in the longitudinal,as well as the transverse, direction of the boat, and they are handmanipulable adjustments which do not require special tools, so the usercan readily make the angular changes while on the water.

Also, the optimum angle of forty-five degrees for the scoop bottom 28with the water surface "S" can be gaged by the top edge of the plate 23being aligned with the pieces 18, as shown in solid lines in Fig. 3. V

To, further affect the water entering the. scoop 27,

means such as the shown compression coil spring 32 are provided betweenthe scoop sides 29 to be disposed in the stream of water coming upthrough the scoop, 27. The means or spring 32 thus intercepts the streamof water and disintegrates it to where a fine spray is created as thestream flows around and through the spring coils. In the shownarrangement, each of the scoop sides 29 has a trunnion or a boss 33attached to the inside surface thereof to project inwardly and present amounting. boss which is received by the inside diameter of the spring32, and thereby the bosses retain the spring 32 in its shown position.The spring would actually vibrate or flexunder the pressure of the waterstream, and this would further disintegrate the stream into a desiredspray at the outlet side of the scoop 27. Obviously, othermeans could beused in place of the spring 32' such that the means disintegrates thestream of water in the scoop.

While a specific embodiment of this invention has been shown anddescribed, it should be obvious that certain 1.
